Is the number 0 a natural number?

Normally I have always taken the Natural Numbers to start at 1 and not to include zero. Natural Numbers are 1,2,3,4,5, [] and Whole numbers are 0,1,2,3, According to Wikipedia: In mathematics, a natural number is either a positive integer (1, 2, 3, 4, ) or a non-negative integer (0, 1, 2, 3, 4, ).

Also know, why is zero not a counting number?

Zero is known as the neutral integer, or the whole number that comes in the middle of the positive and negative numbers on a number line. Zero does not have a positive or negative value. Zero is however considered a whole number, which in turn makes it an integer, but not necessarily a natural number.
